Bully in the (Embedded) Playground
As the dust begins to settle, it's interesting to consider this question: Why has Microsoft's Embedded group aimed their big guns at embedded Linux at this time? Here are some clues:
Clue number one: Microsoft is losing to Linux in the general embedded market. A number of market studies, such Evans Data Corporation's “2001 Embedded Systems Developer Survey”, have consistently begun to report that tremendous strides have been made by embedded Linux over the past one to two years.
Specifically, Evans Data Corporation's latest data says that embedded Linux was the third-most popular OS choice for new embedded system designs among 500 developers polled in 2001--behind Wind River's VxWorks and Microsoft's DOS, and ahead of Microsoft's WinCE (see Figure 1).
Of greater significance, though, is that the results of the study suggest that embedded Linux is poised to jump into first place, ahead of both Wind River's and Microsoft's offerings, within the next 12 months.
Clue number two: the stakes are extremely high in emerging “post-PC devices” markets. Another likely reason for Microsoft's growing concern with embedded Linux is that major manufacturers like Hewlett-Packard, Sharp and Motorola recently have begun delivering new consumer devices that contain embedded Linux. These include handheld computers and TV set-top boxes—emerging markets with extremely high-volume potential, which Microsoft undoubtedly wants to dominate.
In the PDA space, where Microsoft has steadily gained ground on market-leader Palm, embedded Linux may well be perceived as a “dark horse” disruptive technology. This is especially of concern given the growing popularity of embedded Linux in the Far East, where most high-volume consumer products are manufactured.
In contrast to the handhelds market, there is no established leader in the emerging markets for set-top entertainment systems and auto-PCs. These markets clearly have the potential to absorb more OS royalty stickers than desktop PCs, so it is not surprising that Microsoft would want to nip the early embedded Linux lead in the bud.
Watch for the action to heat up further in these and similar high-volume “post-PC” markets in the coming months. According to rumors from embedded Linux vendors such as Lineo, MontaVista and Red Hat, there are literally hundreds of embedded Linux-based consumer devices in the pipeline—products that can't be discussed publicly until they're about to be shipped by their manufacturers.
All in all, 2002 promises to be another exciting year for embedded Linux!
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
